ABSTRACT:
A snorkel top device which may be readily added to an existing snorkel tube for preventing the inadvertent entry of splash water into the top of the tube by providing a flap which tends to deflect splash water so that it exits the snorkel top device without entering the tube attached thereto. The most significant feature of the invention is that the snorkel top device provides a simple and effective guard against entry of splashed water into the top of the snorkel tube and yet constitutes a unitary, relatively inexpensive structure which has no moving parts, no valves and which provides an aesthetically pleasing addition to existing snorkel tubes.
